Your Mercedes-Benz Key, Made Where the Car Is
A Mercedes-Benz without a working key is not going anywhere. We fix that on-site in Prosper, usually in one visit.
Mercedes-Benz keys depend on the car's security system. Many older FBS3 keys we can make on-site; newer FBS4 keys often have to be ordered through Mercedes. We check your VIN and tell you which one you have before you pay for anything.
In Prosper we usually meet Mercedes-Benz owners in Star Trail, Downtown Prosper and Lakes of Prosper. If the car is in a garage, give us the level and spot number.
Almost everything in Prosper is new, from Windsong Ranch to Star Trail. That means two things for us: smart keys for new cars, and rekeying new homes so the builder's keys no longer work.
New Prosper homes often come with a builder keypad deadbolt. We can reset the codes or swap it for a smart lock.
Our vans come into Prosper on Preston Road and the Dallas North Tollway extension, and we also cover Celina, Frisco and McKinney next door. The Mercedes-Benz models we see most around here are the GLS, G-Class and Sprinter.
